We had again a busy development cycle with many new drivers as well as
lots of core improvements / cleanups. Let's go for highlights:
ALSA core:
- PCM locking scheme was refactored for reducing a global rwlock
- PCM suspend is handled in the device type PM ops now; lots of
explicit calls were reduced by this action
- Cleanups about PCM buffer preallocation calls
- Kill NULL device object in memory allocations
- Lots of procfs API cleanups
ASoC core:
- Support for only powering up channels that are actively being used
- Cleanups / fixes of topology API
ASoC drivers:
- MediaTek BTCVSD for a Bluetooth radio chip, which is the first such
driver we've had upstream!
- Quite a few improvements to simplify the generic card drivers,
especially the merge of the SCU cards into the main generic drivers
- Lots of fixes for probing on Intel systems to follow more standard
styles
- A big refresh and cleanup of the Samsung drivers
- New drivers: Asahi Kasei Microdevices AK4497, Cirrus Logic CS4341
and CS35L26, Google ChromeOS embedded controllers, Ingenic JZ4725B,
MediaTek BTCVSD, MT8183 and MT6358, NXP MICFIL, Rockchip RK3328,
Spreadtrum DMA controllers, Qualcomm WCD9335, Xilinx S/PDIF and PCM
formatters
ALSA drivers:
- Improvements of Tegra HD-audio controller driver for supporting new
chips
- HD-audio codec quirks for ALC294 S4 resume, ASUS laptop, Chrome
headset button support and Dell workstations
- Improved DSD support on USB-audio
- Quirk for MOTU MicroBook II USB-audio
- Support for Fireface UCX support and Solid State Logic Duende

The migration scanner is a linear scan of a zone with a potentiall large
search space. Furthermore, many pageblocks are unusable such as those
filled with reserved pages or partially filled with pages that cannot
migrate. These still get scanned in the common case of allocating a THP
and the cost accumulates.
The patch uses a partial search of the free lists to locate a migration
source candidate that is marked as MOVABLE when allocating a THP. It
prefers picking a block with a larger number of free pages already on
the basis that there are fewer pages to migrate to free the entire
block. The lowest PFN found during searches is tracked as the basis of
the start for the linear search after the first search of the free list
fails. After the search, the free list is shuffled so that the next
search will not encounter the same page. If the search fails then the
subsequent searches will be shorter and the linear scanner is used.
If this search fails, or if the request is for a small or
unmovable/reclaimable allocation then the linear scanner is still used.
It is somewhat pointless to use the list search in those cases. Small
free pages must be used for the search and there is no guarantee that
movable pages are located within that block that are contiguous.

The prepare_fb call always happens on new_plane_state.
The drm_atomic_helper_cleanup_planes checks to see if
plane state pointer has changed when deciding to call cleanup_fb on
either the new_plane_state or the old_plane_state.
For a non-async atomic commit the state pointer is swapped, so this
helper calls prepare_fb on the new_plane_state and cleanup_fb on the
old_plane_state. This makes sense, since we want to prepare the
framebuffer we are going to use and cleanup the the framebuffer we are
no longer using.
For the async atomic update helpers this differs. The async atomic
update helpers perform in-place updates on the existing state. They call
drm_atomic_helper_cleanup_planes but the state pointer is not swapped.
This means that prepare_fb is called on the new_plane_state and
cleanup_fb is called on the new_plane_state (not the old).
In the case where old_plane_state->fb == new_plane_state->fb then
there should be no behavioral difference between an async update
and a non-async commit. But there are issues that arise when
old_plane_state->fb != new_plane_state->fb.
The first is that the new_plane_state->fb is immediately cleaned up
after it has been prepared, so we're using a fb that we shouldn't
be.
The second occurs during a sequence of async atomic updates and
non-async regular atomic commits. Suppose there are two framebuffers
being interleaved in a double-buffering scenario, fb1 and fb2:
- Async update, oldfb = NULL, newfb = fb1, prepare fb1, cleanup fb1
- Async update, oldfb = fb1, newfb = fb2, prepare fb2, cleanup fb2
- Non-async commit, oldfb = fb2, newfb = fb1, prepare fb1, cleanup fb2
We call cleanup_fb on fb2 twice in this example scenario, and any
further use will result in use-after-free.
The simple fix to this problem is to block framebuffer changes
in the drm_atomic_helper_async_check function for now.

In VRR mode, keep track of the vblank count of the last
completed pageflip in amdgpu_crtc->last_flip_vblank, as
recorded in the pageflip completion handler after each
completed flip.
Use that count to prevent mmio programming a new pageflip
within the same vblank in which the last pageflip completed,
iow. to throttle pageflips to at most one flip per video
frame, while at the same time allowing to request a flip
not only before start of vblank, but also anywhere within
vblank.
The old logic did the same, and made sense for regular fixed
refresh rate flipping, but in vrr mode it prevents requesting
a flip anywhere inside the possibly huge vblank, thereby
reducing framerate in vrr mode instead of improving it, by
delaying a slightly delayed flip requests up to a maximum
vblank duration + 1 scanout duration. This would limit VRR
usefulness to only help applications with a very high GPU
demand, which can submit the flip request before start of
vblank, but then have to wait long for fences to complete.
With this method a flip can be both requested and - after
fences have completed - executed, ie. it doesn't matter if
the request (amdgpu_dm_do_flip()) gets delayed until deep
into the extended vblank due to cpu execution delays. This
also allows clients which want to regulate framerate within
the vrr range a much more fine-grained control of flip timing,
a feature that might be useful for video playback, and is
very useful for neuroscience/vision research applications.
In regular non-VRR mode, retain the old flip submission
behavior. This to keep flip scheduling for fullscreen X11/GLX
OpenGL clients intact, if they use the GLX_OML_sync_control
extensions glXSwapBufferMscOML(, ..., target_msc,...) function
with a specific target_msc target vblank count.
glXSwapBuffersMscOML() or DRI3/Present PresentPixmap() will
not flip at the proper target_msc for a non-zero target_msc
if VRR mode is active with this patch. They'd often flip one
frame too early. However, this limitation should not matter
much in VRR mode, as scheduling based on vblank counts is
pretty futile/unusable under variable refresh duration
anyway, so no real extra harm is done.

A bit bigger than normal for this week due to fixes for some long
standing display issues that are bound for stable. These changes would
be going to stable anyway, so I figured it was better via 5.0 than 5.1.
- Several display fixes
- Fix PX systems due to core changes in runtime pm

When a dce80 asic was suspended, the clocks were not set to 0.
Upon resume, the new clock was compared to the existing clock,
they were found to be the same, and so the clock was not set.
This resulted in a blackscreen.

[Why]
If the cursor pos passed from DM is less than the plane_state->dst_rect
top left corner then the unsigned cursor pos wraps around to a large
positive number since cursor pos is a u32.
There was an attempt to guard against this in hubp1_cursor_set_position
by checking the src_x_offset and src_y_offset and offseting the
cursor hotspot within hubp1_cursor_set_position.
However, the cursor position itself is still being programmed
incorrectly as a large value.
This manifests itself visually as the cursor disappearing or containing
strange artifacts near the middle of the screen on raven.
[How]
Don't subtract the destination rect top left corner from the pos but
add it to the hotspot instead. This happens before the pos gets
passed into hubp1_cursor_set_position.
This achieves the same result but avoids the subtraction wrap around.
With this fix the original cursor programming logic can be used again.

On HP ProBook 4540s, if PM-runtime is enabled in the radeon driver
and the direct-complete optimization is used for the radeon device
during system-wide suspend, the system doesn't resume.
Preventing direct-complete from being used with the radeon device by
setting the DPM_FLAG_NEVER_SKIP driver flag for it makes the problem
go away, which indicates that direct-complete is not safe for the
radeon driver in general and should not be used with it (at least
for now).
This fixes a regression introduced by commit c62ec4610c
("PM / core: Fix direct_complete handling for devices with no
callbacks") which allowed direct-complete to be applied to
devices without PM callbacks (again) which in turn unlocked
direct-complete for radeon on HP ProBook 4540s.

Signed-off-by: Jani Nikula <jani.nikula@intel.com>
When resuming, we check whether or not any previously connected
MST topologies are still present and if so, attempt to resume them. If
this fails, we disable said MST topologies and fire off a hotplug event
so that userspace knows to reprobe.
However, sending a hotplug event involves calling
drm_fb_helper_hotplug_event(), which in turn results in fbcon doing a
connector reprobe in the caller's thread - something we can't do at the
point in which i915 calls drm_dp_mst_topology_mgr_resume() since
hotplugging hasn't been fully initialized yet.
This currently causes some rather subtle but fatal issues. For example,
on my T480s the laptop dock connected to it usually disappears during a
suspend cycle, and comes back up a short while after the system has been
resumed. This guarantees pretty much every suspend and resume cycle,
drm_dp_mst_topology_mgr_set_mst(mgr, false); will be caused and in turn,
a connector hotplug will occur. Now it's Rute Goldberg time: when the
connector hotplug occurs, i915 reprobes /all/ of the connectors,
including eDP. However, eDP probing requires that we power on the panel
VDD which in turn, grabs a wakeref to the appropriate power domain on
the GPU (on my T480s, this is the PORT_DDI_A_IO domain). This is where
things start breaking, since this all happens before
intel_power_domains_enable() is called we end up leaking the wakeref
that was acquired and never releasing it later. Come next suspend/resume
cycle, this causes us to fail to shut down the GPU properly, which
causes it not to resume properly and die a horrible complicated death.
(as a note: this only happens when there's both an eDP panel and MST
topology connected which is removed mid-suspend. One or the other seems
to always be OK).
We could try to fix the VDD wakeref leak, but this doesn't seem like
it's worth it at all since we aren't able to handle hotplug detection
while resuming anyway. So, let's go with a more robust solution inspired
by nouveau: block fbdev from handling hotplug events until we resume
fbdev. This allows us to still send sysfs hotplug events to be handled
later by user space while we're resuming, while also preventing us from
actually processing any hotplug events we receive until it's safe.
This fixes the wakeref leak observed on the T480s and as such, also
fixes suspend/resume with MST topologies connected on this machine.
Changes since v2:
* Don't call drm_fb_helper_hotplug_event() under lock, do it after lock
(Chris Wilson)
* Don't call drm_fb_helper_hotplug_event() in
intel_fbdev_output_poll_changed() under lock (Chris Wilson)
* Always set ifbdev->hpd_waiting (Chris Wilson)

code paths and sets the DISPC timings manually.
To fix the problem properly we should move the DSI encoder to the new
encoder model. This will however require a considerable amount of work.
Restore DSI operation by adding back video mode flags handling in the
DSI encoder driver as a hack in the meantime.

Commit edb715dffd ("drm/omap: dss: dsi: Move initialization code from
bind to probe") moved the of_platform_populate() call from dsi_bind() to
dsi_probe(), but failed to move the corresponding
of_platform_depopulate() from dsi_unbind() to dsi_remove(). This results
in OF child devices being potentially removed multiple times. Fix it by
placing the of_platform_depopulate() call where it belongs.

Reading any of the DSI debugfs files results in a crash, as wrong
pointer is passed to the dump functions, and the dump functions use a
wrong pointer. This patch fixes DSI debug dumps.

Certain SNB machines (eg. ASUS K53SV) seem to have a broken BIOS
which misprograms the hardware badly when encountering a suitably
high resolution display. The programmed pipe timings are somewhat
bonkers and the DPLL is totally misprogrammed (P divider == 0).
That will result in atomic commit timeouts as apparently the pipe
is sufficiently stuck to not signal vblank interrupts.
IIRC something like this was also observed on some other SNB
machine years ago (might have been a Dell XPS 8300) but a BIOS
update cured it. Sadly looks like this was never fixed for the
ASUS K53SV as the latest BIOS (K53SV.320 11/11/2011) is still
broken.
The quickest way to deal with this seems to be to shut down
the pipe+ports+DPLL. Unfortunately doing this during the
normal sanitization phase isn't quite soon enough as we
already spew several WARNs about the bogus hardware state.
But it's better than hanging the boot for a few dozen seconds.
Since this is limited to a few old machines it doesn't seem
entirely worthwile to try and rework the readout+sanitization
code to handle it more gracefully.
